23 Years of FreeDOS (ebook)

On June 29th, 2017, FreeDOS turned 23 years old. There’s nothing special about "23," but I thought it would be great to celebrate the anniversary by having a bunch of past and current users share their stories about why they use FreeDOS. So, I made a call for users to write their own FreeDOS stories. This eBook contains the voices of many of the users who contributed their stories, as well as the history of FreeDOS. Many individuals have helped make FreeDOS what it is, but this eBook represents only a few of them. I hope you enjoy this collection of 23 years of everything FreeDOS! 23 Years of FreeDOS (ebook)

wcd 6.0.1

WCD (Wherever Change Directory) is a command-line program to change directory fast. It saves time typing at the keyboard. Erwin has released wcd 6.0.1. This release fixes a bug in the DOS, OS/2, and Windows versions that was present since version 5.3.3. When a user typed drive and directory name (e.g. wcd d:games), wcd did not find the directory. Also: New Brazilian Portuguese translations have been added for the UI messages and the manual. You can find the new version at the WCD website. See also the full release notes.
